%N A001387 Decimal encoding of a binary "look and say" sequence (A005150). To get 
               the 5th term, for example, note that 4th term has three (11 in binary!) 
               1's, one (1) 0 and two (10) 1's, giving 11 1 1 0 10 1.
%C A001387 I conjecture that the ratio r(n) of the number of "1"s to the number 
               of "0"s in a(n) converges to 5/3 (or some nearby limit). - Joseph
